"To all ich-om t may concern:

Be it known'that l, Joii'N lV. MCCSLAND,

a citizen of'the United States, resding at jcliicago, inthe county ofCook and State of' 5 Illinois, have invented a new and usefulImprovement' in a'. Bumper, of which the .My invention relatestovbumpers or fenders for motor driven vehicles, and com- 0 prisesastructure formed of metal positioned uponits edge orwith' its flatfaces in 'av verticalv planefso as to provide a relative wide protectingarea across the front' o f the vehicle, 'to protect the mud guards,radiator,

' 'l5 laiiips and otherl accessories of the vehicle rom injury," intheevent of collision. vOne of the objects of my invention is the iprovision vof 'a bumper' structure wherein a ;c oinparativelywideimpactfreceiving ele- 2Q.me'nt Aextends acrossxthe width ofl ,the

-v=eh icle,l terminating adj acent' thel plane. 'of fthe' -wheels,virhic h .impact element is provided with frsilient`attaching. meansin the form oflengths of strap metal so connected 25 'totheiinpactstructure that. theattaching means .maybe movedlongitudinallythereon Yfor -the purpose. of adjustment toaccommodate`Athe lbum' r to divers widths .of

I ,bumper so that; the" attachment to4 the .vehicle may-fbe made' at'aplurality ofjloca-4 35 ltions upon each sideof tho-vehicle framej-whereby the-principle. of the cantilever is w employed to hold theimpact member against `excessive vibration. 'Having tlie'forcgomgobjects in -view, my invention comprises the L0 structure'hereinafter'more' fully described andas pointed outin theclaims," reference beingmade to the accompanying drawings i In the drawings:
